1965 was a tricky time to be making a mock documentary about the perils of nuclear war. Ask Peter Watkins: His devastating, 50-minute docudrama about what a nuclear strike on England might be like was so horrific that it was banned by the BBC (which had funded it's creation) for 20 years.

The narration doesn't pretend that what we're seeing is real. Watkins carefully sets up the fact that we're watching a hypothetical examination of the future. But on screen, these don't look like actors. These look like real people, burned, scarred, dismembered, and homeless, thanks to radioactive fallout and the chaos that follows from a nuclear strike.
